Back Stop:

Backstops are fitted inside the reducers of inclined conveyors to prevent the transported items from sliding backwards when a power failure occurs.

Note:

It is important to provide the motor control circuit with a phase sequence protection device to prevent forced rotation in the wrong direction in case of phase sequence reversal.

Brushes:

These driven brushes are used to clean the transport surface of the belt. They are best suited for applications where powders or similar dry items are transported.

Butt Coupling:

Butt couplings are used to fasten conveyors sections together.

Chutes:

Chutes are custom designed to link different conveyors together.

Control Panels:

Control, panels are custom designed according to the requirements of each application. These typically use PLC controllers (Telemecanique or Siemens) and variable speed drives for induction motors.

Cross Bracing (Chassis):

Cross bracings are used with long roller bed conveyors to adjust the alignment of the two side channels, and make them perpendicular to the support rollers' axis.

Deflectors:

Deflectors are placed at some point along a long conveyor to force the transported item off a conveyor and onto another one , or down a chute.

The deflector is a special conveyor that is mounted on a pivot and pneumatically or mechanically operated through a control panel.

Drip Pans:

Drip pans are used to prevent the debris or other items transported to fall on the floor. They can be easily removed cleaned and replaced. They are usually mounted on the supports of the conveyors.

Emergency Pull Chord:

This is a special type of emergency stop , that is installed along the side channel of a conveyor to allow personnel to stop the conveyor from any point along its length.

These are usually used in conjunction with long conveyors, where access to the mushroom type buttons is restricted.

Emergency Stop (Mushroom Self Latch):

These are standard self latch buttons, that will remove all power from the motor circuit. Once pressed they self latch, and must be rotated to release them.

End Stop (Mechanical):    

End stops are used for applications where unit goods must be stopped at some point along the conveyor (or at the end of the conveyor).

Note:

The belt material must be chosen to allow the accumulation action without applying excessive pressure on the transported items.

Feed Hoppers:

These are custom designed to regulate the flow of bulk goods or small items on a conveyor. The exact dimensions and shape depends largely on the physical properties of the items transported.

Front  and Tail Bumpers:

These bumpers are used whenever mobile conveyors are arranged in tandem, to prevent damage to the pulleys resulting from collision between conveyors.

Guard Rails:

Guard rails are fitted along side channels of conveyors to prevent transported items from falling off the conveyors or to force guide them along a certain path.

Head Pulley Hood:

The head pulley hoods are used in conjunction with bulk materials conveyors type TR-2 and TR-3.

They are fitted with a 100 mm pipe coupling ( 4 inch) for attaching to a dust suction unit (provided by the customer).

Individual Side Tables:

Side tables are fitted along the side channels of conveyors to provide for a stable small working surface. These are typically 400 mm x 500 mm.

Inside Scraper:

Inside scrappers are used to sweep of any debris from the inside surface of the return strand of a belt. This will reduce material buildup on the return pulley, thus improving belt tracking.

Longitudinal Side Tables:

These are one-piece tables mounted along the length of a side channel.

They are usually 240 mm deep and of the same length as the side channel module, or conveyor section. Custom designs available on request.

Nose Wheels:

Nose wheels are used to facilitate the transition of smaller  items between two conveyors where the  gap between the head pulley of one conveyor and the tail pulley of the other needs to be bridged.

Optical Switches and Controls:

These are special controls such as optical switches, reflectors mechanical or proximity switches and are mounted on the side channels of the conveyors. They normally feed the control panels of larger systems.

Outside Scraper:

Outside scrapers are usually mounted below the head pulley, to scrape-off materials transported from the belt surface (and drop them inside the head pulley hood).

Pushbutton Stations and Electric Controls:

These are pushbutton stations mounted along side channels. They can be used to control conveyor operation.

Pushers:

Pushers are pneumatic or mechanical devices that are actuated under electrical control to push of transported items from conveyors.

These are custom designed to suite the characteristics of the product.

Side Skirts:

Side skirts are used with bulk materials conveyor to confine the transported item and prevent spillage along the belt sides. They consist of a solid metal frame attached to the side channels, and lined with soft rubber or resin to seal of the gap between the belt and the metal skirt.

Under Trussing:

These are special trusses designed to offer a self-supporting structure to the body of the conveyor whenever the distance between supports is large. These are custom designed according to individual requirements.

Variable Speed Drives:

Electronic drives are used to control many aspects of AC induction motors driving the reducers of conveyors. They offer variable speed typically from 10% to 120% of rated speed, and controlled rate ramp-up or deceleration of the motor, as well as dynamic braking by DC injection. UNITEL uses Telemecanique or Siemens drives, but others are available on request.
